This pattern was ‘invented’ by our SOA-architects team integrating the Oracle SOA Suite and the Oracle e-Business Suite in an existing IT-landscape.
The trickle-feed integration pattern can be used when distributed systems integrate with one another by means of asynchronous messaging. The messages are versioned to each other in such a way that the newest version may only be processed by the receiving system after all older versions of that message are successfully processed.

This blog briefly describes with code examples how you could use DBMS_MONITOR to trace database sessions via a web application, through a pooled connection (more…)

Like most people, the most problems I ran into were during the installation and configuration of the product. Here is a how-to for solving the most of these issues: (more…)
I’ve used my ESB system – installed on SuSE9, connected to a 10.2 E.E. on the same machine – for a few months now, so I thought it would be interesting to take a look at what’s going on in my database schema created by my esb system (oraesb). This led to some questions and raising eyebrows, I hope some of you esb-experts out there might have an answer for or a comment for that matter . (more…)
